There are many champion in the game that do moves that last for a certain duration but you don't always know how much longer it will last.We need timer for individuals and or teams to tick down. For example Jarvan Demacian standard doesn't have a timer that tells you how much longer you or your team can rely on the armor and atk spd buff. It just shows an icon about your abilities that your in its range and getting the buff. No timer on trundles contaminate to see how much longer you will be getting all of those buffs. I'm sure there are many other champions I haven't mentioned but we need to get these things changed in league of legends please reply and vote to help make a change.

So you're saying that being told they last 8 seconds isn't enough?
